SUMMARY
This step-by-step article describes how to use Recovery
Console to recover a Windows Server 2003-based computer that does not
start.
The Recovery Console is a command-line tool that you can use
to repair Windows if the computer does not start correctly. You can start the
Recovery Console from the Windows Server 2003 CD, or at startup, if you
previously installed the Recovery Console on the computer.
Use the Recovery Console on a Computer that Does Not Start
NOTE: You must be logged on as Administrator or as a member of the
Administrators group to perform this procedure. Also, if your computer is
connected to a network, network policy settings may prevent you from completing
this procedure.
To run the Recovery Console, follow these steps:
1.
Configure the computer to start from the CD or the DVD
drive. For more information about how to do this, see the computer
documentation or contact the computer manufacturer.
2.
Insert the Windows Server 2003 CD in the computer's CD or
DVD drive.
3.
Restart the computer.
4.
When you receive the message that prompts you to press any
key to start from the CD, press a key to start the computer from the Windows
Server 2003 CD.
5.
When the Welcome to Setup screen appears,
press the R key to start the Recovery Console.
6.
Select the Windows installation that you must access from
the Recovery Console.
7.
Follow the instructions that appear on the screen, type the
Administrator password, and then press ENTER.
8.
At the command prompt, type the appropriate Recovery
Console commands to repair your Windows Server 2003 installation.
For a list of commands that are available in the Recovery Console, type
help at the command prompt, and then press ENTER.
NOTE: Alternatively, you can install the Recovery Console as a startup
option on the computer so that it is always available. For information about
how to do so, see the Precautionary
Measures section in this article.
9.
To quit the Recovery Console and restart the computer, type
exit at the command prompt, and then press
ENTER.
The following list describes the available commands for the
Recovery Console:
•
Attrib changes attributes on one file or folder.
•
Batch executes commands that you specify in the text file, InputFile. OutputFile holds the output of the commands. If you omit the OutputFile argument, output is displayed on the screen.
•
Bootcfg is used for boot configuration and recovery. You can use the bootcfg command to make changes to the Boot.ini file.
•
CD (chdir) operates only in the system directories of the current Windows
installation, in removable media, in the root directory of any hard disk
partition, or in the local installation sources.
•
Chkdsk: The /p switch runs Chkdsk even if the drive is not flagged as dirty. The
/r switch locates bad sectors and recovers readable information.
This switch implies /p. Chkdsk requires Autochk. Chkdsk automatically looks for
Autochk.exe in the startup folder or in the boot folder. If Chkdsk cannot find
the file in the startup folder, it looks for the Windows Server 2003
installation CD. If Chkdsk cannot find the installation CD, it prompts the user
for the location of Autochk.exe.
•
Cls clears the screen.
•
Copy copies one file to a target location. By default, the target
cannot be removable media, and you cannot use wildcard characters. Copying a
compressed file from the Windows Server 2003 installation CD automatically
decompresses the file.
•
Del (delete) deletes one file. Del operates in the system directories of the current Windows
installation, in removable media, in the root directory of any hard disk
partition, or in the local installation sources. By default, you cannot use
wildcard characters.
•
Dir displays a list of all files, including hidden and system files.
•
Disable disables a Windows system service or a Windows driver. The servicename argument is the name of the service or the driver
that you want to disable. When you use this command to disable a service, it
displays the service's original startup type before changing the type to
SERVICE_DISABLED. It is a good idea to note the original startup type so that
you can use the enable command to restart the service.
•
Diskpart manages partitions on hard disk volumes.
•
The /add option creates a new partition.
•
The /delete option deletes an existing partition.
•
The device-name argument is the device name for a new partition. One
example of a device name for a new partition is \device\harddisk0.
•
The drive-name argument is the drive letter for a partition that
you are deleting, such as D:.
•
Partition-name is the partition-based name for a partition that you
are deleting, and can be used instead of the drive-name argument. One example of a partition-based name is
\device\harddisk0\partition1.
•
The size argument is the size in megabytes of a new
partition.
•
Enable enables a Windows system service or a Windows driver. The servicename argument is the name of the service or the driver
that you want to enable, and start_type is the startup type for an enabled service. The
startup type uses one of the following formats:
Exit quits the Recovery Console and then restarts the computer.
•
Expand expands a compressed file. The source argument is the file that you want to expand. By
default, you cannot use wildcard characters. The destination argument is the directory for the new file. By
default, the destination cannot be removable media and cannot be read-only. You
can use the attrib command to remove the read-only attribute from the destination
directory. The option /f:filespec is required if the source contains more than one file. This
option permits wildcard characters. The /y switch disables the overwrite confirmation prompt. The /d switch specifies that the files should not be expanded and
displays a directory of the files in the source.
•
Fixboot writes a new boot sector on the system partition. The fixboot command is only supported on x86-based computers.
•
Fixmbr repairs the boot partition's master boot record (MBR). The device-name argument is an optional name that specifies the
device that requires a new MBR. Omit this variable when the target is the boot
device. The fixmbr command is only supported on x86-based computers.
•
Format formats a disk. The /q switch performs a quick format. The /fs:file-system switch specifies the file system.
•
Help lists all the commands that the Recovery Console supports. For
more information about a specific command, type help
command-name or
command-name /?.
•
Listsvc displays all available services and drivers on the computer.
•
Logon displays detected installations of Windows and requests the local
Administrator password for those installations. Use this command to move to
another installation or subdirectory.
•
Map displays currently active device mappings. Include the arc option to specify the use of Advanced RISC Computing (ARC) paths
instead of Windows device paths. (ARC is the format that is used for the
Boot.ini file.)
•
Md (Mkdir) creates a directory. The command operates only in the system
directories of the current Windows installation, in removable media, in the
root directory of any hard disk partition, or in the local installation
sources.
•
More/Type displays the specified text file to the screen.
•
Rd (rmdir) removes a directory. The command operates only in the system
directories of the current Windows installation, in removable media, in the
root directory of any hard disk partition, or in the local installation
sources.
•
Ren (rename) renames a single file. The command operates only in the system
directories of the current Windows installation, in removable media, in the
root directory of any hard disk partition, or in the local installation
sources. You cannot specify a new drive or path as the target.
•
Set displays and sets the Recovery Console environment variables.
•
Systemroot sets the current directory to %systemroot%.
How to Install the Recovery Console as a Startup Option
You can install the Recovery Console on a working computer so
that it is available to use if you cannot start Windows. This precautionary
measure can save you time if you must use the Recovery Console.
